BOTTLE-CLOSURE.

Specieation of Letters Patent.

Patented July 17, 1906.

Application filed September 25, 1905. Serial No. 280.078.

Be it known that we, IsAAc CARTER DILKs and JAMES PARK, Jr., citizens of the United States, residing at Cavite, Philippine Islands, have invented a new and useful Bottle- Closure, of which the following is a specification.

This invention relates 'to bottle-closures, and has for its object to provide a closure adapted to be seated in a bottle-neck and to vpermit the free discharge of liquid from the bottle, but to prevent refilling the bottle when once empty.

A further object of the invention is to provide a closure which may be removed from the bottle when the bottle is empty by breaking the neck of the bottle, leaving the closure intact and capable of being reused as often as occasion may make desirable.

`With these vand other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing, any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a view of the improved bottle-closure shown in side elevation mounted in the neck of a bottle shown in vertical section. Fig. 2 is a vertical sectional view of the improved bottle-closure mounted in the neck of a bottle. Fig. 3 is a top plan view of a bottle-neck with the improved closure mounted therein.

Like characters of reference designate corresponding parts in each and every figure of the drawings The improved bottle-closure forming the subject-matter of this application is adapted for use in connection with a bottle having a neck 1, provided with an interior peripheral groove 2. The closure comprises a. valveseat member 3, in which is formed a valveseat 4, with a valve 5 therein mounted. Adjacent its lower end the valve-s eat member is provided with a transverse bore 6, in the outer end of which are mounted bolts 7 with a spring 8 therebetween and arranged to hold the bolts normally in engagement with the groove 2 of the bottle-neck.

At its upper end the valve-seat member is screw-threaded, as at 9, and a cap member 10 is screw-threaded interiorly at its lower extremity to engage with the screw-threads 9 of the valve-seat member. Intermediate its ends the cap member is provided with an annular groove 1 1, with openings 12 forming communication from the interior cavity to the annular groove. The cap member 1() is proportioned to 'lit and substantially ll the bottle-neck 1 and is provided with longitudinal grooves 13, forming communication from the annular groove 11 to and piercing the top. To prevent the cap member being disengaged intentionally or accidentally from the valve-seat member, an aperture 14 is provided at the line of juncture 15, and therein is disposed a Cotter-pin 16, proportioned to contact with the inner surface of the bottle-neck and to be held thereby seated in the aperture 14. For transportation, storage, and sealing purposes the bottle-neck 1 is proportioned to extend upwardly beyond the top ofthe cap member, and in the upper extended end may be inserted a cork or other approved stopper 17.

It will be understood that when the bottle is in an upright position the valve 5 will be seated in the valve-seat 4 to prevent evaporation of contents and also to prevent refilling the bottle when once empty; but when.

the bottle is inverted the valve will gravitate to the normal upper end of the hollow cap, leaving a continuous opening through the valve-seat, the openings 12, the grooves 11 and 13 for the liquid to pass from the bottle outwardly through the neck.

Having thus described the invention, what is claimed is- 1. In combination with a bottle-neck having an internal groove, a valve-seat member provided with spring-pressed bolts arranged to engage with said groove, a valve arranged Within the valve-seat member and arranged to close by gravity when the bottle is in vertical position, a cap member secured to the valve-seat member and having a central recess into which the valve may pass during pouring, said cap member having openings for the passageof the liquid and being pro- IOC vided with spaced longitudinal grooves around its periphery to permit passage of the liquid.

2. In combination with a bottle-neck, a valve-seat member provided with means for engagement with the neck, a valve disposed for cooperation with the valve-seat, a cap member provided with passages .communicating with the valve-seat, and means held by the bottle-neck for retaining the valveseat member and cap member rigidly oonnected.

3. In combination with a bottle-neck having an internal peripheral groove, a valveseat member provided with means for engagement with the groove, a valve disposed 'for cooperation with the valve-seat, a cap member provided with passages communieating with the valve-seat, and means held by the bottle-neck for retaining the valveseat member and the cap member rigidly connected.

4. In combination with a bottle-neck, a valve-seat member provided with means for engagement with the neck, a valve disposed for cooperation with the valve-seat, a hollow cap member provided with passages communicating with the valve-seat, and means held by the bottle-neck for retaining the valveseat member and cap member rigidly connected.

5. In combination with a bottle-neck having an internal peripheral groove7 a valveseat member provided with means for engagement with the groove, a hollow cap member provided with passages communicating with the valve-seat, a valve disposed within the hollow cap member and arranged for cooperation with the valve-seat, and means held by the bottle-neck for retaining the valve-seat member'and the'cap member rigidly connected.

6. In combination with a bottle-neck having an internal peripheral groove, a valveseat member provided with means for engagement with the groove, a hollow cap member provided with an annular groove communicating with the interior cavity and with longitudinal groovesv communicating with the annular groove, a valve disposed within the hollow cap member and arranged for cooperation with the valve-seat, and

the internal cavity by means of openingsv through the cap member and having longitudinal grooves extending from the annular groove to the upper end of the* cap, and a cotter-pin engaging the valve-seat member and the cap member and retained in position by the bottle-neck.

In testimony that we claim theforegoing as our own we have hereto afIiXed our signatures in the presence of two witnesses.
